Spam attacks countered
The game of blogging has become more complicated for me recently as I have been attacked by a new brand of spammer. The shear numbers are overwhelming, adding up to about 200 per day now and growing steadily. I think I must have triggered some machine lists abroad. So I am adding a short math quiz feature to the comments section. The purpose is simply to check that the responder is a human being, not a machine. Thanks for your understanding.
